The carbon nuclear magnetic resonance (NMR) data of the acetyl derivatives of 8‐(1,1‐dimethyl‐2‐propen‐1‐y1) galangin and 8‐(1,1‐dimethyl‐2‐propen‐1‐yl) kaempferide, isolated from Platanus acerifolia buds, have been reassigned unambiguously by HETCOR and COLOC experiments on synthetic compounds. The carbon NMR data for the naturally occurring 8‐(1,1‐dimethyl‐2‐propen‐1‐yl) kaempferide is reported for the first time.
